>                 URL: http://jira.jboss.com/jira/browse/JBPM-681
>             Project: JBoss jBPM
>          Issue Type: Bug
>          Components: Core Engine
>    Affects Versions: jBPM 3.1.1
>         Environment: Java EE with JTA
>            Reporter: Bernd Ruecker
>         Assigned To: Tom Baeyens
>            Priority: Critical
>             Fix For: jBPM jPDL 3.2.2

> If you
> - invoke a SessionBean in a jbpm action
> - jBPM and the SessionBean run in the same JTA transaction
> - a Exception occurs
> Then the Transaction is marked for rollback from the EJB-Container when the Exception occurs in the SessionBean.
> Now jBPM wants to handle the Exception (see http://docs.jboss.com/jbpm/v3/userguide/processmodelling.html#exceptionhandling):
> When an exception occurs in a delegation class, the process element parent hierarchy is serached for an appropriate exception-handler. When it is found, the actions of the exception-handler are executed
> But becaue the transaction is already marked for rollback, a call to Hibernate (lazy loading?) results in a exception:
> 7:14:29,875 INFO  [DefaultLoadEventListener] Error performing load command
